SPRINKLER.

To all lwhom' it may concern:

Be it known that we, GUADALUPE BUELNA and ALFRED REDINGTON PoET'r,citizens ofY the United States, and residents of ySanta Barbara, in'thecounty of Santa Barbara and State of California, have invented a new andImproved Sprinkler, of which the following is aiull, clear, and exactdescription.

This invention is an improved sprinkler as used in sprinkling lawns,etc., relating to sprinklers which are placed at any point` of the lawnand automatically revolved by the reactive force oi `the water andthrowing the same thereabout.

One 'object oi the invention is to produce a sprinkler of this characterwhich is adjustable to throw a spray of waterV at any desired angle,thereby increasing or decreasing the radius at which the major part oithe water falls; or ii desired, the angle may be changed 180 degrees, inwhich case the rotation oi the sprinkler will'be reversed.

Another object of the invention is to` provide. an improved form oinozzle ior the sprinkler to throw a ianlike spray, thereby distrib utingthewater with equality and lightness,

Reference is to be had to the accompanying drawings forming a part ofthis specification, in whichk similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal, central section oi the sprinkler; Fig. 2 isa fragmentary, vertical section taken at .right angles to Fig. l; Fig. 3is a fragmentary view of one of the sprinkler arms and in section, showing the application and construction oi one of the noz-' zles, and Fig.4 is an end elevation of a nozzle.

Referring to the drawing figures, the numeral 1 in' dicatesa suitablebase, preferably oi ornamental construction as shown, and supporting atits center an elbow 2 having a horizontally disposed hose 2, a nut atone end and a vertical threaded aperture 2b at its opposite end.Threaded into the aperture 2b is a short straight pipe 3 having fixed atits upper end an externally threaded cup 4 over which a dished cap 5 isengaged. This cap has, as shown, a vertical extension 6 at its centerfor receiving and rotatably embracing the depending stem 7 of a Tfitting 8. The cap 5 is filled to the bottbm of its threads with leadand then faced off, forming a bearing 9 against which a collar 10,preferably of brass and fixed upon the lower end of the stem 7, isadapted to bear. A shoulder is provided at the juncture of the stem withthe head ofthe T 8 5o and rests onthe top edge oi the extension 6 whenthe water pressure from the sprinkler is removed, sufficient play beingallowed between theseparts to dispense with undue friction;

Seated in a recess in the head of the T 8 over the stem 7 is a pinion1l, s aid pinion having a hole through it of the size of the bore of thestem and freely rotatable Specification. of Letters Patent.Applicationfiiled .I une 13.1906. Serial No. 321.492.

by means of a bossA at one side thereof tting in the recess. Theopenings in the ends of the T 8 have collars 12 threaded into themthrough which pass axially rotatable arms .13 of the sprinkler. Theopposed ends of'these arms in the T 8 have fixed to` them pinions 14 ofequal size meshing with thepinion l1 at diametrically opposite points.The arms, us shown in 1 and 3, are curved in opposite directions attheir outer ends when -theyare in proper mesh with the pinion 11 andhave threaded extremities to which is attached our improved nozzle. Eachof these nozzles comprises a cap 15 threaded onto the outer end of eacharm and having a perforation 16 at its center countersunk from theoutside from which leads a V-shaped slit 16 with outwardly bevelededges. The nozzle on each arm is held in proper relation therewith by ajam nut 17 which is manually adjusted, as is also the nozzle, byperipheral knurled flanges formed thereon. v

In theluse of the sprinkler, a hose or otherpipe leading from any sourceof water supply is connected with the elbow 2 at 21 and the sprinklerseated on the lawn.'

The pressure of the water in the cup 4 forces -the brass collar10`against its lead seat and prevents any leakage of the waterthereabout. The reaction of the force of the water is imparted to thearms 13 which revolve on the stern 7 as a center, throwing a fan-shapedspray from the Vnozzle circumferentially about the sprinkler.

If it is desired to increase or decrease the radius of the throw of thewater for each arm respectively, one of the arms 13 can be revolved atan angle to the horizontal, which, through the intermediary of thegearing, will revolve the other arm at a corresponding angle but in thereverse direction, thereby increasing or decreasing the range oi thewater according as -to whether the nozzles are projected above or belowthehorizontal. This increase of range will be at a maximum when thenoz-- zles are pointedV upward at an angle of 45 degrees. By revolvingthe arms axially, carrying the nozzles 180 degrees, the rotation of-thearms canbe reversed, whicl is of advantage in sprinkling at the cornerof the house or hedge, in that water 'is thrown at different Asidesthereof for each direction of rotation.

1f it is desired that the nozzles do not rotate, they should-be axiallyturned to lie ina vertical plane with their arms, where they will ceaseto revolve. This use of the sprinkler will be found desirable inwatering narrow strips of lawn or borders.

AAlthough we have described the invention embodying our preferred formof construction, itis evident that the details thereof can be modifiedas desired; and We consider that we are entitled to such changes` asfall within the scope of the invention as claimed.

Having thus described our invention we claim as new anddesire to secureby Letters Patent:

(v1. ln a sprinkler, a base, un elbow connected to the center thereof, ushort, vertical pipe threaded luto the elbow,

leadin the,cap, a pinion seated in a recess in the T a cup supported atthe upper end of the pipe, a dshed cap over the cup, a lead hearing inthe top of the cup, a T having 'a vertical spindleA rotatable in the capand having a brass 520i-lar at the lower end thereof bearing on the overthe stem thereof, a collar threaded into each end of the T, arms havingreversely curved ends passing through` the collars. a pinion fixed tothe opposed ends of the arms, and in mesh with the pinion seated in theT, and noz! zles carried at the outer ends of the arms.

2. In a sprinkler, the combination of avsupport through which water isadapted to be conducted, a T rotatably mounted on said support, a stemcarriedA by the T, a lead bearing about the stem, means fixed at the endof the Vstem for pressing on the bearing and preventing the withdrawalof the T," a pinion rotatably mounted in the T, arms having pinionsfixed' at the opposed ends meshing with the pinion in the 'I," said armshaving reversely bent ends, and nozzles carried by said'reversely bentvends, for the purpose described.

3, A sprinkler comprising arms each having a curved outer end lying inthe same plane as itsrespective arm, a

ber. in which said arms are journaled and inclosing said pinions, and apinion revolubly seated within said member and meshing with the pinionsfixed to said arms.

4. A sprinkler comprising arms, a revolble member in which said arms arejournaled, a pinion ixedv t0 the inner end of ea'ch arm and inclosedwithin said member, and a pinion rotatably mounted within said memberand meshing with the pinions fixed to said arms.

5. A sprinkler comprising a base, a T verticaliy and revoluble supportedon said base, collars threaded in the opposite ends of said T, an armjournaled in each collar, a pinion fixed tothe inner end of each armwithin the T, and a pinion seated within th'e Tnndmeshing with thepnions fixed to the arms. v
